Example scenario of using an aluminum alloy lever hoist: The wind turbine tower maintenance team selects a 3-ton aluminum alloy hoist because its own weight is only 9kg (compared to the same specification steel one at 16kg), which reduces the burden of carrying it in high places. Combined with anti-rotation chains, it avoids torsion issues during the installation of blade components. Through reasonable selection and standardized use, the aluminum alloy lever hoist can improve work efficiency while ensuring safety, making it particularly suitable for the requirements of tool lightweighting and environmental adaptability in modern engineering.
